Enum ThemeChangeEvent 

#[non_exhaustive]
pub enum ThemeChangeEvent {
    Changed,
}

A signal that the OS theme has changed.

This enum carries no theme data – it is a notification only. When you receive an event, call SystemTheme::from_system() to read the updated theme.

Non-exhaustive

Future versions may add new variants. Always include a wildcard arm:

match event {
    ThemeChangeEvent::Changed => { /* ... */ }
    _ => { /* handle future variants */ }
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Changed

The OS theme changed.
